Application filed November 29, 1918. Serial No. 264,630.

T0 all whom t may concern Be it known that I, WALTER T. FLING, a citizen of the United States, residing at Savannah, in the county of Andrew and State of Missouri, have invented certa-in new and useful Improvements in OilBurn ers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention Vrelates to hydrocarbon burners, and aims to provide a novel and improved burner for consuming kerosene or other distillates or oils.

It is the object of the invention to provide such a burner comprising a novel construction andassemblage of the component elements, whereby the burner is rendered practical, efficient and particularly useful in cook stoves, ranges and the like, although the burner can be modied for use in furnaces, water heaters, steam boilers and elsewhere.

A further object is the provision of a burner which can lbe manufactured at small cost and theparts readily assembled as well as being readily taken apart for purpose of cleaning, repairing or replacement, the main parts of the burner being readily cast from suitable metal.

A still further object is to provide novel means for generating the oil or liquid fuel into vapor in starting the burner and after the generator or retort has been primed, so that the vaporization is started effectively and continued.

With the foregoing and other objects in view, which will be apparent as the invention is better understood, the invention resides in the construction and combination of parts as hereinafter described and claimed, it being understood that changes can be made within the scope of whatV is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein:

Figure l is a plan view of the improved burner.

Fig. 2 is an end view.

Fig. 3 is a longitudinal vertical section taken on the line 3-3 of Fig. 1.

Fig. tis a cross section taken on the line a-fi of Fig. 3f, A

carrying out the invention, the bodyV 1 of the burner is bowl-shaped, and `elongated as shown, and provided with a central depression or cavity 2 through one end wall of which is threaded or otherwise linserted a mixing tube 3 that projects into the depression 2 for delivering the mixture of v apor and air into said depression so as to rise within the body or bowl 1. An air entry 'casing 4f is threaded or otherwise engaged upon the jouter end of the mixing tube 3, and has air inlet openings 5 controlled by a rotatable shutter or valve 6 to control the supply of air as desired.

A burner head or top 7 is disposed within themouth or rim `of the top 1, and is provided with a series of slots 8 therein, preferably disposed obliquely from .side to side as clearly seen in Fig. 1. These slots are for the' outlet of the mixture upwardly therethrough from. within the body and distribute the flames over the area of the burner head or top 7 which is concentric within the body and similar in shape. The head or top 7 has its margin extended downwardly, outwardly, and upwardly to form a. marginal trough 10 for holding a charge of priming fuel to start the burner. It is preferable to provide an asbestos wick 111 within the trough 10 for holding the fuel and facilitate the priming operation. The outer wall of the trough l0 fits snugly within and against the rim of the body or bowl 1, so as to support the head or top 7 which rises from within the surrounding trough. The burner head or top 7 is preferably provided with a longitudinal reinforcing rib 9 extending from one end tothe other and d e-v pending from said head or top between the ends of the slots 8, and said slots extending into the rib 9, as seen in Figs. 3 and 4. p,

A shield 12 of the same form as the top of bowll is seated on the rim thereof, the lower edge portion of the shield being offset outwardly, as at 13, so as to seat on the edge of the body and removably support the shield. The shield, as shown, curves inwardly so as to overhang the priming trough 10, and said shield is provided near its lower edge or immediately above the offset portion 13 with air inlet apertures 14, which admit lair into the shield to pass over the trough 10 and to the slot-s 8. These apertures 14 are located at intervals throughout most of the periphery of the shield. This shield 12 as well as the body 1 and head or top 7 can be readily cast suitable metal, althouglfi they can rounding the slotted portion of the burner l head or top 7, so that this coil will surround the iiaines above the slots S to be heated thereby after the burner is started and the coil in being disposed over the .trough 10 will be quickly heated by the priming fuel which burns within said troughin starting the burner. The shield 12 protects the coil or tubing 15 and also confines the flames so that'they will not'spread from the body or bovvl 1, and said shield is a'lso useful as a support for liettles or other objects to .be heated, inasmuch as they can be seated on the upper edge ofthe shield over the iiames. In addition, the shield -`12 also supports the generator or retort. Thus, a clip 16 ein braces the coil 15 at one end of the shield, and is secured to said endfof the shield 4by a bolt 17 or other -securing element, thereby supportingthe coil at this point. The other -end of the shield 12 has notches 18 in its upper edge through which the terminals of the coil or tubing 15 project outwardly below the upper edge of the shield, and said terminals are seated in said notches to support the i coil.

A fuel supply pipe 19 isconnected to one terminal of the coil 15, and has a valve 20 for controllingithe .flow of fuel into the coil or generator. The other terminal of the coil 15 is Vextended downwardly, as at 21, and has a jet or nozzle 22 slipped into the casing 4, theidischarge of vapor from the nozzle 22 being controlled by a suitable valve 23. The vapor issuing from the nozzle 22 passes through the casing 4 into the IniXingtube 3 and sucks in air through the openings 5 which Willadmix with the vapor, so that a proper mixture forced into the body.

In starting `the burner, a small quantity of `priming fuel is poured in the trough 10 and will be absorbed by the asbestos Wick 11 therein. Then, by lighting ythe priming fuel, the flames will rise and heat the coil 15 so that when ,the :valve 2O is opened and fuel Copiesvof this patent may ybe obtained'for'vecents each, by addressingthe AGominssnloner of Patents,

admitted into the coil, the fuel will be vapor-ized and will-discharge from the nozzle 22, thus supplying the mixture which is forced up through the slots 8 to support the flames when the mixture issuing from said slots vis ignited. The ooil15 in surrounding the iield of flames will be kept hot so as to continue the generation of vapor.

Having thus described the invention, what is claimed as new is:- Y

1. A burner embodying a bovvlshaped body, a top having vapor outlets and a marginal priming-fuel trough surrounding the outlets and fitting Within the rim of the body and a generator coil-above saidtrough having an Aoutlet communicating with the body -to deliver vapor thereinto.

2. A burner embodying a bowl-shaped body, a top having a raised portion With vapor outlets, and a marginal priming-ifuel trough surronnding said portion and vfitted Within the rim of lthe body, and a generatingcoil above said'trough and having a delivery end communicating With'the body `to deliver vapor thereinto.

B.- A burner embodying a bowl-shaped body, atop having vapor outlets and a marginal 'priming-fuel trough surrounding Said outlets and Vfitting Within fthe `rim `of `the body, a shield supported `over said rim, and a generating coil Within the shield above said troughfand lhaving an `outlet .for delivering vapor into the body. 4. A burner embodying a `bowl-shaped body, a mixing tubefor delivering vapor into said body,.aztop having a raised portion with vapor outlets and afsurrounding marginal `priming'-fuel trough fitting within the rim ofthe body, a shieldsupported on `the edge of said rim and overhanging said trough, l and :a generating coil `supported by and Within the shield over said trough and having an outlet'nozzle to direct the vapor into the mixing tube. v

Intestimony whereof `I have signed my name to this specification in the presence of tivo subscribing lWitnesses.
